Application filed June'i, isos. serai No. 435,917'.

To ally-'whom it may concern: Be it known that I, GEORGE ject ofthe Emperor JAooBs,a sub- Ohio, have invented One object o'f theinvention is to provide means for individually and collectively connecting and gearing the leavesso that, when folded forward to a prone position, removed from the case, they are adapted to be collocated or assembled face to facein a rectangular pack, within a spacel substarlri tially combined depth of all the leaves, so that in this relation the entire series without consuming undue space therein.

A further object of. the invention is to provide means for automatically moving vthe upright leaves-forward or backward at the same time the leaves in front of themare lowered or raised, so that the lower end of the foremost one of the up'ri ht leaves always voccupies the saine vertica plane and is, therefore,

conveniently accessible for inserting and reV from the moving bills at the same distance forward sideof the cabinet.

Another object of the invention is to pro'- vide means for counter-balancin the series of leaves to hold them, individua ly and collectively, in the normal so that when one upward from the prone position, they `are automatically thrown to and then remain yin e l 1 edges ofthe adjoining leaf at a point above the upright position. l l

These general 'objects and other subsidiary advantages, are attained by the conart hereof, in whic in f igure 1 is a perspective view 4of the cabinet, showing the leaves in their normal nearly vertical or upright position; Fig. 2, a vertiof Germany, residing at4 Alhance, in the county of Stark and State of a new and useful Filingl Cabinet, of which the following is a specifica-- of a retail mer-` equal to the area of one leaf andthe,

of leaves can'be readily inserted in a safe or vault for security of the edge; and the upright position, .and or .more leaves are started cal-longitudinal sectionof the case, showing an end elevation of the series of leaves in their normal upright position; Fig. 3, a similar section, showing some of the leaves rotated forward to their prone position g Fig. 4, an end elevation of the leaves removed from the cabinet and collocated in a rectangular pack; Fi 5, a fragmentary perspective view of one lin: and the corner of the upper rear leaf; Fig.v 6, a detached perspective view of one slide bracket; Fig.v 7, an inside elevation of ythe same; 8, a detached side elevation Aof one sprin ever; and Fig. 9, a side elevation of one" edbearing.

Similar numerals refer to similar parts side and end rims 10 and 10n and the relatively thin middle plates- 11, vthus forming recesses in eacliiface of the leaves clips 12 in the usual manner. The normal lower edge of each leaf is formed round'in its rear quadrant l13 and substantially sqiiare in .the case 1, tlf/e The leaves 2 and 2a' are preferably formed I ,with the .for the filing 0f hais which are, heid hy 'the f its forward quadrant 14, tlius presenting the Y' substantially flat face 15 in the forward half pivot pins or trunnions 1=6.and 16a are provided on each inner-end corner of the leaf substantially in the axis of the rounded uadrant of the lower edge. The Anormally ower ends of the leaves .ire hinged or connected together by means Of the links 3, the rear end of each link being forward end' being pivoted at 17 to the side the tiunnion, with reference tothe adjacent lower edge of the leaf. This manner of hinging andconnecting the leaves ermits them to be assembled, face to face, inechelon, as shown iii Figs. 1 and 2, and also to be collocated in a rectangular pack, as shown iny Fig. 4.

Each Slide bracket 4 h, provided oh its 110 pivoted on the trunnion of one leaf, .and the of theA series,

outer sides with the longitudinal groove 18 hold the bracket in 20 of the vlever 5 is adapted to operate. The

inner wall of the bracket is extended upward 4tofform the plate 2 1 on the inner rear side of which is formed the iiange 22 and on the inner forward side, the' lug 2 3. A corre- Svpplnding a'n'ge 24 and a lug 25 are provided onthe lower .portion of each end edge of the rearmost leaf, which flange and lug 4 are ada ted to fit in the socket formed by the flange and lug of the bracket', the bracket flange being curved in its lower portion 26v to fit the correspondingly curved lower 4portion 27 of the leaf iian e, and is also provided with the s uare s oulder 28 which is adapted to abut t `e end 29 of the leaf flange, whereby the lrearmost leaf Vis securely held i in an upright position, the bracket being Aso shapedas to tilt the leaf slightly backward at its upper en d from a true vertical position. Y

The U-shaped slotO isl provided in the Wall of each brackct' to receive the trunnion 16a Vof the rearmost leaf. The trunnions -16a are extended to protrude outside the walls'of the brackets, and the rollers 31 are preferably provided on these eXtendedends,

`which rollers are adapted-to operate in the forked ends, as 20, of the levers. One lever is pivoted, as at'32, on each side wall of the case, and the lower end of the lever is drawn 4forward by the energy of the retractive spring 6, which is connected in the forward part of thecase at 33.

The leaves are placed in the case in their upright osition by insertin the flanges and lugs of tfie rearmost leaf in t e sockets of the slide-brackets, with the trunnions thereof in the forked ends ofthe levers, and by inserting the trunnions of the foremost leaf in the U-shaped bearings of the case. In this relation, the upper leaf is held forcefully backward by the action of the springs and levers, and by the same action each successive leaf is likewise held upward and in a slightly backward inclined position against the leaf in its rear, by reason ofthe fact that the line between the link pivots asses above the lower forward corner of t e rear leaf. The backward inclination of the `respective leaves also. assists in preventing them from tilting forward. Furthermore, the forward fiat portion 15 and the corner 14 of the lower side-edge of the foremost upright leaf, which is adapted to rest either on the shelf 9 vthe case of the first leaf, or on the upper ace of the adjoining prone leaf in case of an intermediate leaf, servesto prevent a rotation of the foremost leaf, for the reason that such a v rotation must first raise the leaf a distance equal to the protrusion of the corner beyond the radius o the rounded rear quadrant of the lower edge; It is evident, however, that one ormore of the leavescan be rotated forward by forcefully overcoming'theresistance of the rotru the li connectlons and of the spring llevers and in so doing, the foremost leaf israised a slight distance to rotate itover its. rotrudingcorner of the lower-ed e and allv t e other leaves are drawn forward connecting links, so that the nextleaffwhich now becomes the foremost upright leaf, will 'be brought forward into a position 'directlyabove the position formerly held `bythe last rotated leaf; It is furthermore evident thatv when one or more leaves have been rotated upward by manual means a portion o'f the distance toward the .upright position,'the levers and sprmgs will complete the movement and throw the leaf upward to abut the next leaf in its rear. AThe tracks 7 are inclined slightly'downward toward the front of the case, to accommodate the slight difference in corner of the flowenedgafof by' mean'sifof the the vertical distance between the trunnions -f 'of the'leaves when in their upright and prone positions. The rearmost leaf is adapted to be eld constantly in its' upright position when in the case; but it is evident that by removing thelea'ves from the case, which is preferably accomplished by merely bringing them all to the upright position, and then lifting'the rearmost and foremost leaves out of tlie'respective sockets and bearings, the leaves are'..

adapted to be assembled together, lface to face, in a rectangular ack, as shownin Fig. 4, in which relation tllfey 'are adapted to bc stored in a comparatively 'small receptacle. .Itis evident that either the rearward inclination of the u right leaves or vthe square quadrant in the ower edges of the respective leaves can be employed in combination with means for forcing the rearmost leaf backward, to normally hold the leaves in upright position; and also that either one or both of these methods can be employed without the latter means, but in this event the rotation of,the leaves upward after they are started will not beautomatic, until they have nearly reached their upright position. It is furthermore evident that 1t is not necessary to round the rear quadrant of the connected edges of the leaves.

The improvements in filing cabinets which are illustrated and described but not broadly claimed herein, are made the subject-matter of generic claims in three several prior applicatlons for Letters Patent, led' respectlvely August-17, 9.907,'Serial N o. 388,966 N ovember 18, 1907, Serial-.Nor`402,585 and May 25, 1908 Serial No. 434,866.
